Response Prediction in EBV-HLH Using Metabonomics Analysis

Response Prediction in EBV-HLH Using Metabonomics Analysis

Hemophagocytic lymphohistiocytosis (HLH) is a rare, poorly recognized and underdiagnosed syndrome of excessive immune activation, which is rapidly fatal. Epstein-Barr virus (EBV) is a common trigger of HLH, particularly in Asian individuals. We aim to analyze metabolomics and cytokine profiles of patients before and after treatment to explore the metabolomic characteristics of EBV-HLH, and search for pathogenic mechanisms and therapeutic targets.

Without early intervention, the median survival time is less than 2 months.Epstein-Barr virus (EBV) is a common trigger of HLH, particularly in Asian individuals.
